OSFMount 是一个支持光盘镜像和内存虚拟盘创建装载实用小工具。OSFMount这个软件特色在于，既可以加载光盘镜像，也可以创建内存虚拟盘。
OSFMount 还支持创建RAM 磁盘分区，也就是能够在内存中分割出一块地方虚拟成硬盘空间，这个空间速度将会非常快，对于需要高速读取磁盘的应用程序、数据库、浏览器缓存或者游戏而言，这个功能显得非常重要。第二个好处是安全，磁盘内容全在内存中，系统一关闭内容便会消失。
OSFMount 还支持CD镜像的映射，就是一个虚拟光驱。

OSFMount allows the analysis of disk images with OSForensics. OSFMount can be used to mount
local dd image files that are bit for bit copies of a disk partition. Analysis of the image
file is then possible with PassMark OSForensics by using the mounted volume drive letter. By
default, the image files are mounted as read only so that the original image files are not
altered.
OSFMount supports RAM disks, basically a disk mounted into RAM. This generally has a large
speed benefit over using a hard disk. As such this is useful with applications requiring high
speed disk access, such a database applications, games (such as game cache files) and
browsers (cache files). A second benefit is security, as the disk contents are not stored on
a physical hard disk (but rather in RAM) and on system shutdown the disk contents are not
persistent.
OSFMount supports mounting images of CDs, which can be useful when a particular CD is used
often and the speed of access is important.
